ANTOINE GROUVELLE AND EMILE BELOT, OF PARIS, FRANCE.

IVIACHINE FOR MOLDING FILLERS FOR CIGARS.

SPECIFICATION forming part of Letters latent N o. 636,660, dated November '7, 1899. Application filed December 2, 1897. Serial No. 660,537. (No model.)

T0 all whom, if may concern:

Be it known that we, ANTOINE GnoUvELLE and EMILE BELOT, citizens of the Republic of France, and residents of' Paris, France, have invented certain new and useful Improvements in Machines for Molding the Fillers of Cigars, of' which the following is a specifica# tion.

This invention has been patented by us in Belgium, No. 127,387, dated April 5, 1897; in

rreat Britain, No. 8,893, of 1897, and in Germany,'No. 102,524, dated April 26, 1897.

In our application for patent filed in the United States Patent Ofiice September l1, 1896, Serial No. 605,493, We have described a cigar-bunch-making machine characterized by the combination of a series of mechanical organs or parts which allow the simultaneous or su ccessive operation of first bringing or presenting the open mold in front of the operator, then placing the two parts of this mold into their mutual relation, and when itis filled and closed submitting it to a series of oscillations for the purpose of doing away with the seams or burs of the bunch, to trim the ends of same, and to drive the molds so filled into a slide, where they remain under pressure until they are carried to the drying-place, an arrangement of rack movement permitting the piling or stacking of such a number of molds as may be desired into the same compartment or pigeonhole for the purpose of easier transportation.

The operator is obliged to go through the following operations: first, to handle the mold in seizing it; second, to open the mold; third, to fill the mold; fourth, to close the mold; fifth, placing the molds under pressure, and the same operations in their inverse order.

The present invention aims at various improvements on the machine which was the subject of our said former application for the purpose of molding said cigar bunches of long-cut, short-cut, or scrap tobacco, either dry or moist, without the necessity of the operator touching the molds either for the molding of the bunch or for taking the completed cigar-bunch out of the molds or for pressing the bunches which are in the molds.

For a better understanding of the invention we refer to the drawings herewith, in which- Figure 1 is a side eleva-tion of the machine.

Fig. 2 is a front elevation. Fig. 3 is a crosssection along the line 3 3 of Fig. 4, showing also the rear view of the machine. Fig. 4 shows a general plan of the machine. Fig. 5 is a view in partial elevat-ion of Fig. 1 on a larger scale. Figs. 6 and 7 are details illustrating two extreme positions of the jaws which hold the molds in place. Fig. 8 represents a View in partial front elevation, showing more in detail the parts which produce the opening of the molds and the mechanical taking out of the bunch from the molds. Fig. 9 is a detail view of theparts on the upper left-hand corner of Fig. 8 as seen from above. Fig. 10 is a view in longitudinal section, showing the same parts as the preceding figure. Figs. 11, 12, and 13 are detail views showing the action of the parts which procure the opening of the molds for the purpose of' permitting the removal of the bunches from the molds mechanically.

The same reference letters and n u merals refer to the same elements in the various figures.

The machine consists of a frame comprising the four feet or standards X and the two longitudinal tables X X2, which support tables Z Z2, where the operator lays out on one side the leaves serving for wrappers and on the other the tobacco which serves to make the fillers or interiors for the cigar-bunches.

The machine is so arranged as to work as desired in either of the three following manners: first, with engagement by the pedal or treadle X3 and automatic disengagement after one turn of the shaft of the operating-cams; second, in continuous operation by pressing on the pedal or treadle XS and omitting the automatic disengagement; third, in connection with a machine of any kind which rolls the bunch automatically.

In the first two arrangements the bunch is on the side of this gear, operates at every turn on the cam or finger h', so as to bring about automatic disengagement or throwing out of made by hand by the operator, who feeds it IOO gear. The shaft l) actuates the shaft B by means of the bevel-gears b5 b4. The molds x are made of wood or any other suitable material and consist of two half molds or sockets of even form whose hollow profile governs the shape of the cigar to be made. The compartment or pigeonhole which confines the bunches formerly filled bythe machine,which bunches are ready to be taken out, is placed into a receiver A, Figs. 3 and 1, in such a manner that the pusher A', which is as long as the compartment and a little shorter than the molds, drives a whole row of molds upon the endless belt B5. The rammer or pusher A' is connected by the two links or rods A2 A2 to the rammer or pusher N'. Itis actuated by the lever A5, which oscillates or rocks on the axis A4. The lever A3 carries at A5 a lever AG under tension of a spring A12, the heel of which lever A5 can engage a notch AT of a lever AS, which rocks loosely on axis A4. r1`he lever A8 is controlled by a rod A5, connected to a crank A10 on the shaft B. The extremity A" of thc lever A5 is engaged under the heel of the lever M', which rises at the completion of each twenty-five turns, as will be seen farther on. The endless belt B', which is intended to carry the full molds coming forth from the compartment or pigeonhole A is actuated by the drum B2 (sec Figs. Lland 10) and passes on the guide drum or pulley B5. The drum B2 has on its axle a ratchet-wheel B", (see Fig. 10,) which is actuated by the pawl B5, carried by the lever B5,pivoted at Bland moved by the roller B5, which bears on the cam B9. The molds which have thus been pushed along bear against the vertical wall of the hinge C. The door C' swings around the hinge C upon the upper surface of the mold, while the hooks C2 C2 snap upon the vertical surfaces of the upper half-mold. The door C' is actuated by the levers C5 C4 and bellcrank C5, the latter being pivoted at C9 and carrying the friction -roller C5, which is pressed bythe spring C7011 the cam C8. The lever Clis, guided in its movement by the link C, hinged at C12. (See Fig. 5.) The closing mechanism of the door C' is the same as that described hereinafter for the door HX, which appears clearly in Fig. 5. Simultaneously the finger C10, iixed on the lever C4, liberates the heel of the lever D', pivoted at D2 and actuated by the spiral spring D3. (See Fig. 8.) The rods D4D4, which are pivoted to the lever D', raise the curved needles D5 D5, which are pivoted at DG D5. These needles penetrate a little into the ends of the bunch which is ready to be taken out of the mold. At that moment the door C' comes back and carries between the hooks C2 C2 the upper half-mold. The hooks C2 C2 bear with their heels 1 1 on the tappets 2 2, and the half-mold, which has been brought back by the door C', is then completely free. Figs. l1, 12, and 13 show clearly this action of the hooks C5 C2 for opening the molds. In Fig. 11 the half of a right side is shown in accordance with Fig. 13 and represents the two halves ma: of the mold applied one on the other at the moment when the door C', pivoting around the hinge C, turns down on the upper half-mold. Then the door turns down, the hook C2, which is drawn on bythe spiral spring 23, sets on the vertical surface of the upper half-mold. Theleft half of Fig. 11, corresponding with Fig. 12, represents the two halves of the open mold, the door C' having brought back the upper half-mold held between the two hooks C2. At the same time the heels l of these hooks C2 strike against the lixed pieces 2, and the hooks are thrown out, thus releasing the half-mold. Then the half-molds :t :1c have been driven off by the longitudinal rammers or pushers G G, as described hereinafter, the door C' rises and carries along the hooks C2, and the latter, which are released from the pieces 2, snap on the vertical surface of the door C', which thus limits their movement. The ends of the hooks are inclined, so as to slide upon and engage a fresh half-mold. The needles or pins D5 D5 have held the bunch in the lower half-mold, and as the mold is opened by the hooks C2 C2 the gripper comes down to take the bunch left in thelowcrhalf-mold. The part E of the gripper is fixed on the 1ever E2. The part E' is pivoted to the lever at E5 and is pressed toward the part E by a spring F". (See Figs. S, 9, and 10.) The lever E2 is pivoted at E5 and is actuated by the lever E5, which carries a friction-roller E7, pressing on the cam E5, under the tension of a spring e. On the back of 'the lever E2 a lever F2 is hinged at F, and the extremity F' of this lever is in position to be pressed bya finger F5, whereby the movable part E' of the gripper can be moved by the extremity F2. The finger F3 is fixed on the piece F4, sliding horizontally under the action of the lever F5, pivoted at F5 and moved by the connectingrod F7, which is pivoted at F8 to the lever B5, operated by cam B,as hereinbefore described. When the tongs or gripper descend upon the bunch, they are open. They close by means of the mechanism above described, taking tight hold of the bunch, which rises with the gripper into the position shown by Figs. 1 and 2. A moment later a new opening movement of the gripper produced by the boss F9 of the cam B9, Fig. 10, releases the bunch, which falls from the gripper. The two empty halfmolds, from which the bunch has been taken out, are now in front of the extremities of the pushers G G, which push the half-moldsinto the position indicated by II H' by a horizontal lrectilinear movement. The rammers or pushers G G are iixed on the piece G', which is actuated through a connecting-rod G2 by an elbow-lever G5, swinging around the axis Gand the sliding rod G5, moved by the crankpin G5, which is keyed on the shaft B. The spiral spring GT returns the rammers or pushers G to their rear position. (See Fig. 2.) The operator thus has in front of himself at point IOO IIO

H H two open half-molds and rolls roughly a cigar-bunch which is placed into the halfmold at H' while holding the bunch at the two ends. Then the machine is thrown into gear by means of the treadle or pedal X3. When the bunches are rolled by machinework, the receiver or pusher of these machines is 'arranged over the half-mold at point H', which shall hold the bunch. In this case the mold-machine is mechanically' connected with the bunch-rolling machine. As soon as the bunch is placed into the half-mold at I-Ithe door HX, pivoting around the hinge h, lifts the half-mold at I-I, which it turns down on the half-mold at H', thus inclosing the bunch. Thefdoor H is actuated by the rod H3, pivoted on the lever C4. (See Fig. 5.) The fork H3, which carries the two heads h' h3, then pushes the closed and filled mold between the two jaws II3. The fork H3, rocking at H4, is actuated by the lever H3, which carries the friction-roller H3,which presses on the cam H7. (See Fig. The upper jaw I' then closes down upon the mold by the action of the spring I, which acts upon the elbow-lever I3,pivoting at I4. One of the arms of the lever I3 carries a friction-roller I5, pressing on the cam I3. A-projection I7 of the lever I3 presses in this movement on the elbow-lever I3, pivoting at I9 in such a manner as to lift the movable catch 140, which holds the lower half-mold against lateral movement. The two jaws I are provided with spring-pressed movable bottoms or followers, which exert a yielding pressure upon the molds. The lower jaw I2 is iixed to the extremity of the lever J, swinging around the axis J', and this lever J carries the friction-roller J2, which presses on the cam J3 by means of the spiral spring J4. (See Fig. 5.) The cam J3 has a certain number of undulations, which cause the lower half-mold to oscillate in its relation to the upper half-mold. These movements of the molds, the extreme positions of which are shown in Figs. 6 and 7, combined with the progressive vertical pressure imparted by the jaw I', have the effect of forcing into the molds the pieces of tobacco-leaf which form lateral burs or seams where the two half-molds join and to even up the compactness of the tobacco in the bunch. Two sets of shears K K' and K3 K3, one set at each end of the molds, then clip the ends of the bunch which stand out from the ends of the molds. The blades K K' are attached to the arms of the jaw I', and the blades K2 K3 are fixed on the levers K4 K3, turning on the shaft I4, which shaft is actuated by the lever K7, which is operated by the friction-roller K3, which bears against the cam K9. (See Fig. 2.) The rod L, fixed on the plate G', which is actuated in the manner as above stated, then pushes endwise the mold pressed down by the jaws into the slide L'. (See Fig. 4.) During that time the rammers or pushers G, which participate in the same movement, bring two new half-molds into the position indicated at H H'. At that moment the grippers release the bunch which they held and let it fall on the upper surface of the rammer or pusher G, which carries the bunch back in front of the extremity of the piece F4, which comes forward and drives the bunch into the box F40. The mold which has been guided into the slide L' is held there under pressure by the downwardly pressing strips L2 L3, which are guided vertically by the rods Z. The elbow-lever L4 (see Fig. l) pushes, successively, all the molds on the table X' under these strips. The lever L4, pivot-ing around axis L3, is actuated by the counecting-rod L3, which is drawn on by the crank-pin L7, keyed on theshaft b. When the row of molds arranged side by side under pressure on the table X has reached a sufficient length, the last mold strikes a movable spur M, situated at the extremity of the elbow-lever M', which swings around the axis M3. (See Fig. l.) The inclined plane M3 then rises and pushes the friction-roller M4, fixed on the lever M3, keyed on the axis M6, which controls the rack-escapement MT M3. One tooth of the rack M9 is then liberated. This rack glides vertically in the slides m' m3 and carries at its upper part the pigeonhole or compartment N, which thus descends by the height of one mold. The rammer or presser N' has the length of twenty-[ive molds and is as high as one mold. It travels ahead between the table X' and the strips L2 L3, pushing twentyve molds into the pigeonhole compartment N. The pusher N is operated by the same mechanism as A', as hereinbefore referred to. The spur M, brought back by the spring N3, returns to its original position when the pusher N' has come back to its rear position. While the pusher N' has put in place the twenty-five molds, these molds raise slightly the weighting-roller N3, attached to the strip L3 by the connecting-rods N4 N5. In this manner the molds are under constant pressure while they are pigeonholed in the compartment N. When the pigeonhole compartment N is full, it is carried into a drying-place, if necessary. When the bunches have been in the mold for a sufficient length of time and when they are ready to be taken out, the pigeonhole compartment is put on the machine at A, Fig. 4, as before detailed.
